Firefox Add-ons I use - and I am a noob

This post does not comprise of something revealing or astonishing, for a proper list there are many post like this on dzone or lifehacker, but most of them introduced me to new set of plug-ins, here is list of plugins I use in my Firefox - irrespective of underlying OS, and for the impatient , here is the direct link to the addon collection mentioned below

  1. Adblock Plus -- This is something which tops my list and I think every other list of this kind known to mankind not sponsored by google(or some other ad-network) and by far , it single handedly made me fall in love with Firefox among other things
  2. DownThemALL -- A download manager which really accelarated downloads, in it's early days (of my use) it blocks firefox usage of bandwidth when downloading, but now it works like a charm,
  3. LastPass -- I recently (about 6 months) started using this service for syncing passwords after I lost my key to xmarks (formerly foxmarks), and now this is something I use for syncing password across installation, although it is annoying sometimes but with each update(1 occured just before this post) it is becoming better and better
  4. twitterfox -- I used this as my primary twitter client, It is minimalist yet very functional and for me it is most productive of them all (sorry AIR clients, and I say productive not functional)
  5. Xmarks -- I used it as my primary bookmarks sync tool, my only browser is firefox, but it is available (like lastpass ) for other browsers too.
  6. DZone -- DZone is great , really great, I am a long time user of digg, and it is just what I filtered out of digg, digg have some great content , but it will most of the time overwhelm you, this addon is acts as a companion to site and makes voting really easy for digg ,Note for DZone--please make it available for firefox 3.5 beta, this is the only reason I am stuck at 3.0.X release
  7. Skipscreen -- for skipping annoying rapidshare etc., waiting scripts , it automates most of them and also make that infamous diggbar go.
notables, -- I sometime use Video Downloader for downloading flash content because I do not have amazing bandwidth, for instance I am not able to see Mr.Gosling's Toy show just for this reason. and also Greasemonkey.
